Sulphur noun [ Latin , better sulfur : confer French soufre .]
1. (Chemistry) A nonmetallic element occurring naturally in large quantities, either combined as in the sulphides (as pyrites ) and sulphates (as gypsum ), or native in volcanic regions, in vast beds mixed with gypsum and various earthy materials, from which it is melted out. Symbol S. Atomic weight 32. The specific gravity of ordinary octohedral sulphur is 2.05; of prismatic sulphur, 1.96.

» It is purified by distillation, and is obtained as a lemon- yellow powder (by sublimation), called flour , or flowers , of sulphur , or in cast sticks called roll sulphur , or brimstone . It burns with a blue flame and a peculiar suffocating odor. It is an ingredient of gunpowder, is used on friction matches, and in medicine (as a laxative and insecticide), but its chief use is in the manufacture of sulphuric acid. Sulphur can be obtained in two crystalline modifications, in orthorhombic octahedra, or in monoclinic prisms, the former of which is the more stable at ordinary temperatures. Sulphur is the type, in its chemical relations, of a group of elements, including selenium and tellurium , called collectively the sulphur group , or family . In many respects sulphur resembles oxygen.
